The broadcaster, right, whose grandfather Todd Andrews played an active role in the IRA during the War Of Independence, was chosen to be royal tour guide to point out the major sights in Dublin to the monarch and her husband from the heights of the Gravity Bar in the Guinness Storehouse tomorrow.

And he suggested that the queen and Prince Philip, might sip a drop of the famous stout in the bar overlooking the city.

"I will be giving her a tour of Dublin from the height of the Gravity Bar in the Guinness Storehouse. She'll come in with her husband and meet some people.

"I will say there are some great sights we have here. There is the Aviva stadium, where England and Ireland would have met quite recently in a match. For two points, Prince Philip, who won?" joked the popular RTE broadcaster.

"They will have a pint of Guinness poured for them by the master brewer and there will be a bit more history and then they will be gone for their next appointment," said Tubridy.

He added that he hoped the visits by Queen Elizabeth and US President Barack Obama would boost the country's profile around the world.

"'It will be an interesting few days.

"There are 1,800 journalists from around the world covering the queen's visit and then the same again for Barack Obama," he said.

"The international coverage is extraordinary and hopefully they will beam all that beautiful footage of the sights and sounds of this country to the UK and the US and maybe elsewhere around the world."
